6004 Ceramic Bearing Of SSiC Races And Balls+PEEK Cage With High Precision
Description of 6004 SSiC Ceramic Bearing:
1. SSiC races and balls: Are made of highly purified, sub-micron silicon carbide material, can resist corrosion by hydrofluoric acid, which is the most excellent ceramic material with the best corrosion resistance among the known materials.
2. PEEK cage: We adopted British Victrex PEEK material, PEEK material has similar corrosion resistance to ceramic materials, and has a good resistance to radiation, self-lubricating properties, a high degree of wear resistance and other characteristics. The peek cages are injection molded at high temperature, so have high strength, light body.
Performance advantages of 6004 SSiC Ceramic Bearing:
►Key properties of pressureless sintered silicon carbide |
♦ Max Temperature up to 1650℃ |
♦ Low density:3.15-3.18 g/cm3 |
♦ High strength |
♦ Low thermal expansion : 4.0 (10-6/℃) |
♦ High thermal conductivity:120 W/m°K |
♦ High hardness:2800 HV5 |
♦ High elastic modulus: 410GPa |
♦ Superior chemical stability,resistance to acid and alkali corrosion (incld. hydrofluoric acid) |
